Command Center is empty

Hi there.
I have installed the ZoneAlarm personal firewall many times before and never had some problems with it. But now if wanted to install it on my new installed winxp sp3 system. Everything works pretty well until I wanted to open the command center to change the firewall settings. When I pushed the button to open the command center the windows opens but there are no icons no texts nothing but the top line. The firewall functions seem to work because i still get the messages.

So I though something went wrong while the installation. I uninstalled the program and tried it again. Four or five times with serveal version and nothing changes. I also tried the trail version of the new suit. But it is the same with that program. Everything seem to work but the command center stays empty.

I have a similar System running where everything work just perfectly. So does anyone has an idea what can be wrong?
